Yes, ditto on DonV's comment. Nice pics of a really ideal fishing rig. Looks like you're pretty good at R & R, too. Really like those Charger colors...

Like Island Trader, I would typically favor a modern single over twins but you make some interesting points based on your shallow water and maneuverability needs. Like the part swapping bit, too.

I hope you'll post some performance #'s when you get re-powered.

Go with twins. Compare the fuel consumption of the 115 and 130 Etecs.
The comment about 40' bluewater boats having only one engine is disingenous: Most also have sails. Those that don't, have diesels.

Learn how to spell a big word before you use it. I was just giving my opinion so I hardly think I was being disingenuous.

Sorry I should have said the Blue water power boats...still only one engine and being a diesel has no bearing on being reliable...longevity yes.

Pardon my poor typing skills. I didn't use the word in a pejorative sense.

In addition to "(1)lacking in candor, deliberately misleading;" my 1877 Webster's defines Disingenuous as also meaning "(2)unaware or uninformed; naive; ignorant; (3)to speak from ignorance; (4) to omit pertinent information, either willfully or inadvertently"

It was the last meaning I intended. If I offended you, please forgive me, I certainly did not mean to do so.

That never crossed my mind, however I must admit those "powder blue jerseys" and especially the lightning bolts on the helmets were my favorite football uniforms when I was a kid....a long, long time ago, oh yeah, for those too young to remember back in the AFL days.

Glad to see you did not sell her.I talked to you down around big pine key about 4 yrs ago I had the bracketed sceptre with the twin 250's.I switched to 150 optis and
now I get 3mpg or better at cruse the boat would not get
on top with one 250 shut down but it will with the 150's

I was reading on another list and saw where a guy with an 1985 23' Chris Craft Scorpion WA is running twin '05 115 Etecs, and claims 3.3 mpg at 24 mph & 3800 rpms with 19" pitch props. He said he has to change the prop to get up on plane with one motor, though, changing from a 19" to a 15". Nothing on what kind of props, though, or on what his WOT speed is.
I put the data above plus the 115 Etec gear ratio and calculated slip into a prop calculator and came up with 39 mph at 6000 rpms.

This morning in Destin I saw a early 20' Seacraft SF with the wide transom cutout rigged with twin brand new 60hp Mercury 4-strokes. The boat looked good. It was in front of me trailering west on US 98, and had a Mississippi plate on the trailer.

I wanted twins for all the reasons you have listed but still ended up putting a single 250 on my 23 Contender due to the lower cost.
It had a 2005 225 opti on it and I replaced it with a 2008 250 Yamaha HPDI (18 hours) and I have seen a great improvement in economy and speed.
Next repower I will look into twin's though as I still like to have backup when on the water.

Thanks Fr. Frank, the 23' Chris Craft performance is great information. My current thoughts are the Etec 130hp motors may be the best option. They are 15lbs more weight each but have the possibility of getting up one one without a prop change.

I have a pair of 150 etecs on my 23 center console and sometime think I need a pair of 175's or 200's, the boat goes great with the 150's
I would think IMHO that anything smaller would not do so well. with 4 blade props and a little trim I can plane at 18 knts. but when things are flat at 4100 rpm I am cruising at 30 knts and getting a little better than 2mpg.
your boat looks like it has more weight than my center console and I think your performance will suffer a lot , putting too much strain on the smaller engines and decreased life.
